WOVEN PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 691,193, dated January14, 1902.

Application filed October 28, 1901. Serial No. 80,233. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM T. SMITH, a citizen of the United States,residing in Philadelphia, Pennsylvania, haveinvented certainImprovements in Woven Pile Fabrics, of which the following is aspecification.

Myinvcntion relates to that class of fabrics intended to simulate anoriental rug, these fabrics having a cut-pile face with elaboratepatterns both as to figure and coloring and having a plain back on whichthe figure is partially outlined by portions of the pilethreads drawnthrough to the back.

My invention consists of a fabric which can be cheaply produced upon aloom, such as that employed for a Smyrna rug, the essential feature ofthe invention being the means employed to stifien the chenille fur,which constitutes the patterned face of the fabric, and to prevent saidchenille fur from being drawn to the back of the fabric except to thelimited extent desired.

In the accompanying drawings, Figure 1 is an exaggerated section ofapiece of fabric constructed in accordance with my invention, thesection being taken in the direction of the warp; and Fig. 2 is alikeexaggerated section of the fabric, taken in the direction of the weft.

The fabric comprises repetitions of two warp-threads 1 and 2 and threeweft-threads 3, 4, and 5. The warp-threads 1 are separator Warp-threadswhich extend throughout the fabric and serve to separate the face andback weft-threads and also to determine the longitudinal stability ofthe fabric by prevent-- weft-threads 4 are heavy-spun threads, whichconstitute the back of the fabric, and the weft-threads 5 are finerthreads, which lie alongside the chenille-fur weft-threads 3 in the sameshed of binder-warp, and thereby impart stifiness to the bunch ofthreads constituting the core of the chenille, so as to cause the fur orpile ofo the same to stand up well and rise after being depressed,thereby preventing the pile-surface of the fabric from showingfoot-prints. The fine weft-threads 5 also serve to limit the extent towhich the chenille fur can be drawn down by the binding warp-threads 2between the back weftthreads 4. Hence only a limited amount of thechenille pile or fur is visible on the back of the fabric, sufficient tofaintlyindicate the outlines and coloring of the pattern, as in anordinary expensive oriental rug.

In weaving the fabric ashed is first formed by raising the bindingwarp-threads 2 and lowering the separator warp-threads 1, and into thisshed is shot first the chenille-fur weft-thread 3, which is properlyadjusted laterally to accord with the pattern on the preceding chenilleWeft-thread, after which the weft-shot 5 is inserted and beaten up. Theshed is then changed, the binding-threads 2 being lowered and theseparator-threads 1 raised, and the back weft-thread 1 is then shot inand beaten up, these operations being repeated indefinitely.

Having thus described my invention, I claim and desire to secure byLetters Patent- A woven fabric comprising face weftthreads of chenillefur, reinforcing face weftthreads, eachin a shed with one of thechenille weft-threads, heavy back weft-threads, separator warp-threadsinterposed between the face and back weft-threads, and bindingwarp-threads alternating with the separator warp-threads and tyingtogether the face and back weft-threads, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM T. SMITH.
